The high demands that medical products make on materials, process documentation, production quality and cost efficiency can users easily meet by lasers and laser systems from TRUMPF. The Ditzingen-based laser specialist will be exhibiting two applications at COMPAMED in Düsseldorf, Germany. First, the TruLaser Station 5004 workstation together with the TruPulse 103 pulsed laser will be used to join two stainless steel tubes of different diameters. Afterwards, the TruMark 3010 marking laser, integrated into the TruMark Station 1000 marking station, will label the welded tubes with a data matrix code.
The TruLaser Station 5004 laser workstation with the integrated TruPulse 103 Nd:YAG solid state laser uses an electronic stereo microscope in laser processing. In contrast to systems with optical microscopes, the electronic microscope in the TruLaser Station 5004 is not joined to the laser optic; therefore, operators can adapt their view into the microscope and don’t have to reposition themselves when working with different sized workpieces.
To increase the precision, only the laser beam moves; the workpiece stays still. The large workspace is adapted to flexible production in medical technology. For bulkier workpieces in which more space is needed, a cutout in the work plate can be used or the cover can simply be lifted. However while working, the operator must make sure that he and other persons are properly protected against the laser beam (protective glasses/protective clothing; laser class 4).

The TruMark Station 1000 marking station, TRUMPF's most compact laser workstation, is an entry level machine that can produce high quality markings simply, quickly and inexpensively. The TruMark 3010 marking laser is also ideal for any user who wants an inexpensive method for marking individual pieces or small batches. Like all lasers from the TruMark series 3000, 5000 and 6000, the convection air-cooled TruMark 3010 is noted for its modular and compact design. Scanner, laser head and power supply unit are connected to a hybrid cable through a plug-in connector, so the marking laser can be easily integrated into existing production systems. For customers who want to save space or who need a mobile marking system, the TruMark 3010 can be combined with the compact TruMark Station 1000 workstation.
TRUMPF has the right beam source for any application in medical technology production. The feasibility studies that TRUMPF conducts for its customers in the Laser Application Centers determine which laser, which focusing optic and which parameters are best suited for specific applications. In addition to the pulsed lasers from the TruPulse series for welding and the TruMark series for marking, the medical product industry also relies on fiber lasers from the TruFiber series for cutting delicate components. For drilling micro holes, cutting or shaping stents or improving the osteo-integration of implants, short-pulse and ultra-short pulse lasers from the TruMicro series are the tools of choice. Their high-energy pulses, which can be shorter than 10 pico seconds, make it possible to finely process materials such as metals, polymers, ceramics or glass.
The demands that medical products make on materials, production quality and process documentation are high. At the same time, manufacturers are subject to increasing price pressures. In addition, the requirements for biocompatibility and reproducibility of the products, which are frequently subjected to aggressive cleansing and disinfectant agents, are growing. Even the quantities of the individual products vary greatly, especially in companies with heavily diversified product portfolios.
These are conditions that the laser is simply made for. Its diverse uses and its special qualities for cutting, welding and labeling make the laser an indispensable precision tool for manufacturing endoscopes, instruments and medical technology products. In the process, the laser operates contact-free with fast, accurate surgical precision and with high quality, consistent reproducibility. The quality of laser-processed surfaces is flawless. There are no grooves, ridges, burrs or hollows to adversely affect hygiene. Laser-welded seams, as in endoscopy tubes, have a pore-free, smooth surface and the same biocompatibility as the base material. Highly alkaline disinfectants and high-temperature sterilization cannot harm laser markings on instruments.
In addition to the quality of the individual workpieces, consistent reproducibility and the ability to review the production process are essential. TRUMPF lasers guarantee a constant quality in laser processing through their highly developed beam management. All relevant laser parameters such as average output and pulse energy as well as the beam position and beam form can be controlled in the production process. Service technicians at TRUMPF TelePresence Portal can access the machines – regardless of location – online remotely and securely for maintenance purposes.
